Your family members need a value adjustment. The foisting of guilt and anger on you because you used your brain is hardly supportable. In this modern "civilization" we've crafted for ourselves, though, if you don't play the game then you don't get fed. Still, it's not like that's the only job in town.My girlfriend, my parents, they all think I'm retarded and they are mad at me because of what happened. They think it's better to work at a bank completely unarmed, with no body armor, for a paycheck.
On the bank's attitude of disallowing you arms, armor ... they're in a high-risk business and are denying you the ability to protect yourself, or them. They're edicting protection via prayer. Hell, why have a "security" position anyway?
Kudos on having the foresight to see that job for what it was: something you need like another hole in your head (which might well have been the result, at some point, with all the disarming that bank seems to be keen on). Kudos.
